peppiv has asked for the
wisdom of the Perl Monks concerning the following question:
I was curious to see who thought what about image verification technology. You know, the old type in the box what you see in the graphic. If successful, one would then be able to put in their user name and password and get on with a tracked session. Anything to keep out spiders and other crawling programs that might try to gain entry into a system.
I am currently slammed at work with other things and was hoping someone had made a dent in this area with Perl. I'm sure it could easily be done using the GD library. You could generate text at random and use it to create a PNG and verify against itself through user input. You could even drag out predefined words/images from a DB.
Or, is it not even worth entertaining?
